Stevie Wonder Claims That Anyone Who Doesn't Believe in Global Warming Is Blind

At a concert fundraiser for hurricane relief, Stevie Wonder said that love conquers all boundaries, that it doesn't care what ethnicity or sexual orientation you are, and that it doesn't care about your political beliefs. But then, just a few seconds later, he said, "Anyone who believes that there is no such thing as global warming must be blind or unintelligent." Why is it that liberal celebrities can't just be uniting and helpful forces for good in times of national tragedy? Why do they always have to push their belief system and call the other side "unintelligent"?
